Abstract
In the electric vehicle industry, a battery management system is needed when voltages are in the value of hundreds of volts. The battery management system is not only used to estimate the remaining capacity of the batteries but also to prevent various hazards that may occur in case of improper use. The paper offers a review of the battery management system that is used in the modern electric vehicles. The system is described along with its functions including the practical methods for balancing the battery and the type of batteries used in the automotive industry.
